The Cumulus Panyam 450 is an extremely versatile down sleeping bag, perfect for summer alpine use and suitable for all but the harshest UK winter conditions.
Using ultra-light Pertex Quantum for the outer (weighing in at only 29 g/m2) and 450g of 850 cuin Polish goose down, the Panyam 450 is designed for lightweight end uses, where warmth-to-weight is the primary concern. Trapezoidal chamber construction, a shark-fin foot box and an ergonomic design of the hood provide unique comfort. Additionally, Cumulus have added draw cords and tapes to the hood making it more adjustable. It is also equipped with an independent, adjustable elastic collar with velcro fastening.

Advice on Temperature Ratings
Temperature ratings are used to indicate a bags performance and help you decide between models. However, they are subjective and can be greatly affected by factors such as what you're happy to wear (clothing wise) in conjunction with the bag, your health and metabolism, how much you have had to eat or drink, humidity and altitude, the type of shelter used and whether you are using a suitable insulating mat.
As a guide, the "Comfort" rating indicates the range at which a woman gets a comfortable night’s sleep, the "Limit of Comfort" rating indicates the range at which a man gets a comfortable night’s sleep and the "Extreme" rating indicates a range at which a woman is protected from hypothermia. The Extreme rating is basically a survival rating and it is not advisable to rely on this for general use.
